John Loudon McAdam

John Loudon McAdam (23 September 1756-26 November 1836) was a Scottish engineer and road builder who invented "Macadamization", a system that involved building roads with a hard and smooth surface, making them more durable and less muddy. His construction of raised gravel roads revolutionized transport, and he became involved with day-to-day construction as an engineer. One of his improvements, the introduction of tar to bind stones together, was nicknamed the "tarmac". His roads would allow for a more smooth transition of goods.
